I dont hear or read much about them.All I hear about are usual programmers,edge,superchip...etc....I only know 2 people that have the TTS chip and they love them.I cant find any reviews on it or find any posts about them other than the website.Anybody else know much about them?

 

By looking at their website, it looks like they mainly service diesel motors. They do have a chip, (not a programer), that plugs into your PCM. Personally, I don't like having to fiddle around with the PCM. I'd rather have a programmer I can plug into it and program it. As far as power gains, I really don't know. I couldn't find anything relevant to the f150. Lots of people on some other forums like and don't like the chip. I never saw any dyno slips to prove the gains either. If I were you, I'd stick with a superchip. Just my opinion though. Maybe somebody else here can verify it further.
